Add additional pipelines/searches for external events

There are a couple new types of external events that could be potentially ingested by gwcelery in O4, requiring the following tasks in advance:

• Add pipeline=KamLAND as part of emfollow/gwcelery#72 (should use a new field search=PreSN since these should be treated distinctly from Supernova)
• Add pipeline=CHIME and search=FRB (fast radio burst) as part of emfollow/gwcelery#519, needed as well by the GRB/FRB/Magnetar group
• Add pipeline=SVOM as part of emfollow/gwcelery#539 (closed), which should use the already existing search='GRB'
• Add pipeline=IceCube as part of emfollow/gwcelery#750 and would need to add a new field such as search='HEN'

At the moment I don't have templates to instruct ingest either of these alert types, so that will likely have to be solved in a separate issue (in gwcelery temporarily and GraceDB in the long-run).

Edit, Feb 20, 2024

@brandon.piotrzkowski @andrew.toivonen @michael-coughlin I'd like to get a little more organized in handling these issues since there are a couple of requests floating around on this one ticket. Could you please complete the table below with the information that is missing. In particular, what is the input file upload format for each of these new pipelines, are modifications to existing upload formats needed, and then provide a link to a sample file (even if it means uploading it manually to this issue).

Also, could you work amongst yourselves to determine what the priority are for these (1, 2, 3, etc). This should be based on your assessment of each of the new pipelines' technical readiness, ie, the file format is settled and gwcelery is ready to test but you're just waiting on gracedb changes.

Is Complete?	Pipeline Name	Search(es) Name	Input File Format	Changes needed?	Link to file	Priority
❌	KamLAND	PreSN	unknown	unknown	unknown	3
✅	CHIME	FRB	VOEvent	no	n/a	n/a
✅	SVOM	GRB	JSON for now (can convert to VOEvent in gwcelery until they send in that format)	Ingestion via GraceDB (VOEvent for now but eventually JSON)	VOEvent available but no JSON yet	2
❌	IceCube	HEN	VOEvent	Ingestion via GraceDB	Bronze Gold	1
